Abstract

The invention relates to a process for the preparation of low-pressure ethylene polymers by polymerising the monomers in the presence of a Ziegler catalyst system, in which process the solid ethylene polymer obtained is reacted in the melt with additives which are able to form acids by esterification. The ester-forming additives are preferably epoxide compounds.
